What to do: It’s a First Friday weekend!

The Chadds Ford Historical Society is hosting its ninth Annual Winter Plein Air Event at its Barn Visitors Center March 4

There will be something special in the air in Chadds Ford this weekend – art. On March 4, the Chadds Ford Historical Society will host its ninth annual Winter Plein Air Event at its Barn Visitors Center (1736 Creek Road, Chadds Ford, 610-388-7376, www.chaddsfordhistory.org).

The weather appears as if it will be cooperating as the forecast calls for temperatures in the low 30s but no precipitation. If you’re wondering why the weather is a factor in the presentation of an art show it’s because this weekend’s event is not just another art show — it is a plein air event.

“En plein air” is a French expression which means “in the open air.” It is mainly employed to describe the act of painting outdoors, which is also called “peinture sur le motif” (“painting on the ground”) in French.

This weekend, a select group of 25 artists will be creating works of art “en plein air.” After a session of painting in Chadds Ford and the Brandywine Valley, the participating artists will return to the Chadds Ford Historical Society’s Barn Visitor Center to frame and hang their paintings for a special exhibit and art sale.

Visitors are invited to attend the exclusive “En Plein Air Preview Party” Saturday from 5-6 p.m. for a first look at the wet paintings while enjoying wine and hors d’oeuvres with the artists. All the artwork on display will be available for purchase.

Preview tickets are $35 — $15 of which can be applied to an art purchase. Following the preview, there will be a wine-and-cheese reception from 6-8 p.m. which features the regular admission price of $15.

Wine and Cheese Pairings” are being held every Saturday and Sunday in March from noon-5 p.m.

The Chaddsford Winery (632 Baltimore Pike, Chadds Ford, 610-388-6221, www.chaddsford.com) will present an event called “Wine and Cheese Pairings” every Saturday and Sunday in March from noon-5 p.m. each day.

If you want to enjoy a session of skating this season at the Blue Cross RiverRink Winterfest (Delaware Avenue at Walnut Street, Philadelphia, 215-925-RINK, www.riverrink.com), you better act quickly. This weekend is the last hurrah for the rink’s 2016-2017 season. March 5 marks the season finale. When Sunday’s final session concludes, that’s it – that’s the end until next winter.

Unlike most of the suburban ice rinks, RiverRink features only public skating. Ice-skating is the only use of the ice – no hockey leagues, no lessons, just public ice-skating. This winter, RiverRink has taken the ice skating experience on the Delaware River waterfront to another level by once again transforming the annual rink into a bona fide winter wonderland.

Open seven days a week, the Blue Cross RiverRink Winterfest is an immersive winter-themed experience with a popular bar and restaurant called The Lodge, winter beer garden-style landscaping, a brand-new light show, and a retail shopping experience from Art Star Gallery & Boutique.
